ViaKT133 and other chipset form via has problems with pci performance. Threads talking about the problem: http://www.tech-report.com/news_reply.x/3316/1 http://www.tecchannel.de/hardware/817/8.html PCI Latency patch for windows systems: http://www.networking.tzo.com/net/software/readme/faqvl019.htm PCI Latency patch for linux only KT266 (vialat): http://www.cicese.mx/~mirsev/Linux/VIA/vialatency.tar.gz We had problems when tried to capture from several video capture, however, after loading Vialat patch, which modifies several PCI registers, we can capture from three video boards without problems. Although vialat author, Serguei Miridonov, affirms this patch is only valid for KT266 chipset, it seems to be correct for VIA PLE133 chipset. I have tried to get PLE133 datasheet from VIA in order to confirm the vialat validity, but it seems to be impossible :( Bye, Francisco J.
